1. Field of the Invention
The present invention relates generally to a movable mechanism and an assembly thereof, and more particularly to a movable seat and a rail device composed of one or more movable seats.
2. Description of the Related Art
When processing various board materials, for example, boring a stone material, in a conventionally operation procedure, it is necessary to first fix the board material on a processing table face and then set up a rail and then assemble a processing machine on the rail. In this case, the processing machine can be guided by the rail to cut or mill the board material. In another conventional operation procedure, a processing table is first prepared. A rail and a processing machine are previously arranged on the processing platform. Then, the board material to be processed is transferred onto the processing table and secured by a holding device. Then the board material is cut or milled.
In the conventional technique, the rails for guiding the process ing machine are all fixed and cannot be moved or hard to move. Therefore, the conventional rails lack mobility and flexibility.
It is inconvenient to move the rails and processing machine to another site to perform the cutting/milling operation.
SUMMARY OF THE INVENTIONIt is therefore a primary object of the present invention to provide a movable seat, which can be conveniently moved and quickly located and released from the locating state.
It is a further object of the present invention to provide a rail device composed of at least one the above movable seat. The rail device can be conveniently moved and located.
The movable seat of the present invention includes:
-
- a main body;
- an air passage formed in the main body;
- a sucker disposed under a bottom face of the main body and having an air chamber;
- an air sucking passage disposed in the main body, one end of the air sucking passage communicating with the air passage, the other end of the air sucking passage communicating with the air chamber of the sucker;
- an air intake passage disposed in the main body, an inner end of the air intake passage communicating with the air passage;
- a slide passage disposed in the main body and intersecting the air passage or the air intake passage;
- a support column disposed in the slide passage and movable along the slide passage; and
- an operation/control member mounted on the main body for driving the support column to move; when the operation/control member is positioned in a locking position, the support column being positioned in a communication position, whereby the air passage or the air intake passage keeps in a communication state; when the operation/control member is positioned in a releasing position, the support column being positioned in a blocking position to block the air passage or the air intake passage.
Accordingly, the operation/control member can be shifted to control the air to flow through the air passage or not. When air flows through the air passage, the air in the air sucking passage is sucked to the air passage to make the sucker create sucking force. Accordingly, the movable seat sucks and attaches to the surface of an object. When it is desired to move the movable seat, an operator only needs to stop the air in the air passage from flowing so as to stop the sucker from creating sucking force. Therefore, the movable seat can be easily and quickly located or released from the locating state.
The rail device of the present invention includes:
-
- multiple movable seats as aforesaid; and
